Culture before Tools
Or
Tools foster Culture
?
Practices and process determine the activities and behaviours
In turn provide a guide as to what tooling is needed
Many tools are built by pioneers at the bleeding edge of innovation
Often solve specific problems and give a competitive edge
These early tools are built and used in isolation of any specific culture
TOOLS FIRST
TOOLS FIRST
Tools increase consistency, quality and efficiency
Tools can simplify activities allowing them to be easily shared
Tools reduce the cost & risks of practices
When costs are reduced adoption increases
More people using tools means more conversations and ideas shared
Using specific tool doesn’t mean you have adopted a culture
Conversations, collaboration, sharing Ideas about different but related problems
Alignment of ideas form new perspectives
Overlapping perspectives identify new problem domains
New values or guiding principles are defined to align perspectives
Draw parallel to other areas, creates alignment, believe in the concepts
CULTURE FIRST
Cultures will co-opt Practices & Tools that exist to support their principles
Original tooling creates consistent repeatable results & trust
Tools shape the initial cultural landscape
As trust builds and risks reduce enterprises start to adopt the practices
Tooling gaps show as user base widens and use cases increase
Now enter a phase of tooling industrialisation
CULTURE FIRST
INDUSTRIALISATION OF TOOLING
Tools are important to Culture and its adoption
Principles and practices provide a guide for new tooling
Cultures adoption of tooling creates a marketplace of needs
Marketplace supports the industrialisation of improved tools
Improved tools reduce costs further
CULTURE BEFORE TOOLING OR DOES TOOLING FOSTER CULTURE?
Tools help solve & simplify specific problems
Its problems we share
Sharing experiences and knowledge help us align ideas
Culture arises when there are shared Values & Principles
Better tooling is created to support cultural activities
CULTURE BEFORE TOOLING OR DOES TOOLING FOSTER CULTURE?
Tooling is important but not necessary
Culture does develop tooling
